I just pulled and tried to build and here's the error I got:

The same thing happened on both Linux and Mac.

run mach configure.

We should regenerate the js/src moz.build tree if it has changed as part of a top-level build. What's configure going to do that a dual config.status won't?

configure is doing the dual config.status. We don't have rules to do it. I was merely giving a workaround that works and is not a complicated cd $objdir && ./config.status && cd js/src && ./config.status.
